Larger dogs or dogs that are playful after a procedure can develop a seroma at the incision site. These firm bumps under the skin at the incision and are not painful. Sometimes they can drain and be fluid-filled. They will go away completely as healing takes place, but it may take a little longer than the normal 10 days for healing. It is still there after 2 weeks, begins to ooze any fluid, or gets noticeably larger, then I would have it rechecked. It's unlikely to be a hernia, particularly if it resolves on it's own. For some dogs, warm (not hot) compresses applied a few times per day can be helpful.

Thank you for submitting your question regarding Chloe. The surgical site is still swollen. It may be the suture material that was used under her skin incision. As long as she is eating, drinking and acting normal, she is likely recovering well. Continue her medications as directed. If the swelling becomes worse, discharge comes from the site or she starts acting sick, then please seek veterinary care right away. I hope this information helps!

There can be some residual fluid buildup at the site of the incision, or even a reaction to the suture material that is buried under the skin. Monitor for all of the things that you've mentioned - pain, pus, redness, and swelling, as well as general lethargy or lack of appetite. If the lump hasn't resolved completely by 2 - 3 weeks after the surgery, get Harley rechecked by your vet.

It looks as though Lucy's incision healed very well. The lump you are feeling is likely the suture material. Sometimes the body can react to the suture material and form lumps. If there is no evidence of infection, like you described above, I would continue to monitor the area. Ensure no heat, swelling, pain, drainage, or progression of the lump. If these signs do occur, she should be evaluated by a veterinarian.

Hmmmm...six months is a long time after surgery to see a suture reaction or a seroma (fluid-filled area underneath the skin). I suspect your dog may have a small hernia or opening in the abdominal wall. When we do abdominal surgery (which a spay is) we have to cut through three layers of tissue. First the skin. Under that, the fat. And finally the body wall, which is muscle and connective tissue. Subsequently, when we finish the surgery and close the incision, we stitch all 3 layers separately. Rarely, one of those, typically the body wall, doesn't heal all the way and a small opening into the abdomen is left. These need to be attended to, since a piece of the bowel can lodge itself in the hole and cause a blockage or strangulation. Call the vet who did the operation and talk to him or her about your concern for this complication, and schedule a follow up.
